Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

Cosmic microwave background is a sea of radiation that provides us with evidence for the big bang. When around 1916 Einstein first used general relativity to build a cosmic model, he followed the ...

A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and the Planck satellite, offers a high-definition view of the early Universe.

A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard ...
